Description
Technical field
The utility model belongs to farm machinery transmission art field, relates to a kind of belt pulley, relates to a kind of convex flat key belt pulley of farm machinery specifically.
Background technique
Belt pulley is used for Long Distant Transmit power, and in machinery, a lot of place all needs to use.Flat key belt pulley in farm machinery, comprise spoke, wheel hub and wheel rim, wheel hub is connected with axle sleeve, as shown in Figure 1, traditional belt pulley, generally adopts matrix flat key to be separated combination drive mechanism with key, adopt such structure, can cause following defect and deficiency: manufacturing procedure is many, processing technology is complicated, and manufacturing efficiency is low; On the other hand, matrix flat key is separated combination with key and there is gap, can loosen easy wearing and tearing when rotating, and reduces working life; Also have matrix flat key to be separated with key combination assemble with axle time, easily leak fitted key, impact use.
Model utility content
To be solved in the utility model is eliminate flat key belt pulley matrix flat key in prior art to be separated combination with key, causing when rotating key to loosen easily wearing and tearing, reducing the technical problem in working life, providing one to make key not easy to wear, transmission is effective, the convex flat key belt pulley of long service life.
In order to solve the problems of the technologies described above, the utility model adopts and provides a kind of convex flat key belt pulley, comprise wheel rim, spoke and wheel hub, described wheel hub arranges axle sleeve, inside described axle sleeve, protruding part is set, the axle matched with axle sleeve arranges concave shaped portion, and the matching form of the concave shaped portion on the shape of described protruding part and axle closes.
Above-mentioned convex flat key belt pulley, the protruding part inside described axle sleeve and axle sleeve are formed in one.
Further, above-mentioned convex flat key belt pulley, the protruding part inside described axle sleeve is that a stamping-out is shaping, and processing is more convenient like this.
Further, above-mentioned convex flat key belt pulley, described protruding part is convex flat key.
Above-mentioned convex flat key belt pulley, described wheel hub and axle sleeve are welded as a whole structure.
The utility model compared with prior art has following beneficial effect: 1, manufacturing procedure is few, and processing technology is simple, and manufacturing efficiency is high, and material is saved, and one time stamping-out is shaping; 2, belt pulley and key are an entirety, and when rotating, key can not loosen, long service life; 3, belt pulley and key are an entirety and axle when assembling, and there will not be the situation of leaking fitted key; 4, utilize belt pulley of the present utility model, transmission is effective, has broad application prospects at agricultural mechanical field.
Accompanying drawing explanation
Fig. 1 is conventional belt wheel construction schematic diagram.
Fig. 2 is the utility model convex flat key belt pulley and axle cooperating structure schematic diagram.
Fig. 3 is the utility model left view.
Drawing reference numeral illustrates: 1-wheel rim, 2-spoke, 3-wheel hub, 4-axle sleeve, 5-protruding part, 6-axle, 7-concave shaped portion.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Convex flat key belt pulley as shown in Figure 2 and Figure 3, comprise wheel rim 1, spoke 2 and wheel hub 3, described wheel hub 3 arranges axle sleeve 4, inside described axle sleeve 4, protruding part 5 is set, the axle 6 matched with axle sleeve 4 arranges concave shaped portion 7, the matching form of the concave shaped portion 7 on the shape of described protruding part 5 and axle 6 closes, and when after the concave shaped portion 7 on axle 6 with the position alignment of the protruding part 5 on axle sleeve 4, axle 6 can prolong axle sleeve 4 and do longitudinal sliding motion, as further improvement of the utility model measure, the protruding part 5 inside described axle sleeve 4 is formed in one with axle sleeve 4, in order to easy to process, protruding part 5 inside described axle sleeve 4 can be once that stamping-out is shaping, such manufacturing procedure is few, processing technology is simple, manufacturing efficiency is high, material is saved, as a kind of embodiment of the present utility model, described protruding part 5 is convex flat key, because belt pulley and convex flat key are an entirety, when rotating, convex flat key can not loosen, long service life, pulley drive is effective, and belt pulley and convex flat key are an entirety, when belt pulley and axle 6 assemble, neglected loading is there will not be to join the situation of convex flat key, can avoid affecting quality of product, convex flat key belt pulley as shown in Figure 2, wheel hub 3 and axle sleeve 4, by the structure that is welded as a whole, make wheel hub 3 and axle sleeve 4 more firm like this, improve the quality of products further, have broad application prospects at agricultural mechanical field.
By reference to the accompanying drawings the utility model mode of execution is explained in detail above; but the utility model is not limited to above-mentioned mode of execution; to those skilled in the art; can also do some modification and improvement not departing under prerequisite of the present utility model, these also should be considered as belonging to protection domain of the present utility model.
